PYTHON — Functions

Overview

Functions group reusable code and accept parameters.

What you'll learn

• def
• parameters
• return
• default values

Syntax

def add(a,b): return a+b

Example

def greet(name="Guest"):
    return f"Hello {name}"

print(greet("Ali"))
print(greet())

Notes

• Keep functions small.
• Return values instead of printing when possible.
